Hello friends,

When I was a child, I often visited a small local bookstore. The whole floor was covered in red carpet, and we had to take off our shoes before entering. Inside, it felt more like a quiet, cozy library — where you could sit or lie down and read as long as you wanted.

One day, I found a translated book on electronics.

It was based on Forrest M. Mims III’s "Getting Started in Electronics."

I had no background at all, but I understood it — and I was hooked. The illustrations, the simplicity, the way he used basic components to build real circuits — it left a lasting impression.

I kept going back to that bookstore, reading for free. And whenever I had leftover money from my allowance, I would buy a book or two to keep reading at home. Looking back, I realize how much I absorbed from those moments — not just knowledge, but also a way of thinking.

About 20 years later, I finally had enough skills to create a website of my own: ElecCircuit.com — a place where I could share what I have learned through hundreds of simple, practical electronics articles.

I try to keep it just like that bookstore — open, quiet, and welcoming to anyone who wants to learn.

If you have enjoyed the content or found it helpful, you are welcome to support this work by grabbing an eBook or buying me a coffee.

Most of the eBooks are based on website articles — expanded, clearly illustrated, and polished for easy offline reading.

There is no pressure — just a way to help keep this little corner of the internet alive.

Thanks for being here. You are always welcome. 🙂
